We are one of the few creatures on this planet that can change our diet if we deplete a food source. We have also been able to engineer drugs to fight off disease instead of relying on evolution to combat microorganisms. With minimal natural predators, we have few ways to keep our species for growing exponentially.

This is the problem. There are probably hundreds, if not thousands, of families like this. There needs to be a cap. Me and the girlfriend talked about it. Things we work out, we get married, we have 3, MAX. After that, one of us are getting nipped up because after 3, MAYBE 4, you are being irresponsible. Personally, I'm happy with 2, but not opposed to 3. 4 is pushing it a little too far, IMO.
